Thousands of Venezuela volunteers begin preparing US aid entry

Thousands of volunteers in Venezuela will begin mobilizing on Sunday to bring American aid into their crisis-hit country despite a blockade by President Nicolas Maduro who claims the assistance could be cover for a US invasion. Once-wealthy Venezuela is gripped by a power struggle between socialist leader Maduro and Juan Guaido, the head of the National Assembly who proclaimed himself interim president last month and now has the backing of more than 50 countries.
